MAD

Meaning

Affected by a serious mental illness, or feeling intense anger.

Origin

The word 'mad' carries ancient echoes, tracing its lineage back through Old English gemæd(e)d, meaning 'to make mad,' and further to a Proto-Germanic root signifying 'to change' or 'to alter.' This linguistic journey reveals that the earliest sense of 'madness' wasn't just about derangement, but about a profound alteration of one's normal state—a deviation from the expected. Over centuries, this core idea branched into our modern understanding, encompassing not only mental affliction but also intense anger, wild enthusiasm, or even foolish recklessness, all stemming from that primal sense of being profoundly 'changed' from one's ordinary self.

Examples
